Nazir said he was with his wife at the Aldi food store at North 76th Street and Villard Avenue Monday night when an armed man walked in and told everyone they were being robbed.

"He had the weapon up, looked like an extension of his arm. So it was pointed at the cashier and he waved it around at us, but it was pointed right to her head," Nazir said.

Nazir said he received his concealed carry license two weeks ago and took a refresher course over the weekend.

He said as the robber grew more agitated, he backed up, took his gun from its holster before he another customer in his line of fire.

"There was a gentleman behind the suspect, I nodded for him to get out of the way. Thank God he saw and got out of the way, and that's when I had to fire at the gentleman," Nazir said. "The cashier was fearing for her life, I was fearing for my life as well as many other people. I did what I could, got a good shot off. Thankful he survived and was caught a short time after."

The robber, who was hit in the leg, and a getaway driver were both arrested and are awaiting charges.

This is the first time someone in Wisconsin has foiled a robbery since concealed-carry law went into effect last fall.

Part of the law allows businesses to ban concealed weapons. The Aldi store did have a sign telling people weapons were not allowed.

Nazir said he didn't see the sign until after the shooting.

He met with prosecutors Thursday and said they told him he he won't be charged.

"This one worked out for the positive. (The) bad guys were caught and still living. I'm glad I don't have that on my conscience," Nazir said.
